1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

BZL101 is an aqueous extract from the Scutellaria barbata plant shown to have anticancer properties in a variety of human cancers. In order to determine its efficacy on human reproductive cancers, we assessed the responses of two human breast cancer cell lines, estrogen sensitive MCF7 and estrogen insensitive MDA-MB-231, and of two human prostate cancer cell lines, androgen sensitive LNCaP and androgen insensitive PC3 which are human cell lines that represent early and late stage reproductive cancers. BZL101 inhibited reproductive cancer growth in all cell lines by regulating expression levels of key cell cycle components that differ with respect to the cancer cell phenotypes. In early stage estrogen sensitive MCF7 cells, BZL101 induced a G₁ cell cycle arrest and ablated expression of key G₁ cell cycle regulators Cyclin D1, CDK2 and CDK4, as well as growth factor stimulatory pathways and estrogen receptor-α expression. Transfection of luciferase reporter plasmids revealed that the loss of CDK2, CDK4 and estrogen receptor-α transcript expression resulted from the BZL-dependent ablation of promoter activities. BZL101 growth arrests early stage androgen sensitive LNCaP cells in the G₂/M phase with corresponding decreases in Cyclin B1, CDK1 and androgen receptor expression. In late stage hormone insensitive breast (MDA-MB-231) and prostate (PC3) cancer cells, BZL101 induced an S phase arrest with corresponding ablations in Cyclin A2 and CDK2 expression. Our results demonstrate that BZL101 exerts phenotype specific anti-proliferative gene expression responses in human breast and prostate cancer cells, which will be valuable in the potential development of BZL-based therapeutic strategies for human reproductive cancers.
